As part of an Oculus Connect keynote presentation today, Facebook CEO Mark Zuckerberg rolled out the name "Meta" as a new corporate identity reflecting the company's "new north star—to help bring the metaverse to life."

The name, which Zuckerberg noted comes from the Greek word for "beyond," is "a new company brand to encompass everything that we do." That means the company will be "looking at and reporting on our business as two different segments, one for a family of apps and one for work on future platforms," he said.
